具有双色噪声耦合的定态几率密度

Stationary state probabity density with two coupling colored noise

利用频带宽度微扰技术研究了具有乘法色噪声和加法色噪声驱动系统的动力学行为 ,推导了准确到外噪声关联时间τ定态几率密度 ,并应用于对称势阱模型 .结果表明 。

This article utilized the technique of frequency broadhand perturbation to research the dynamic behavior of the system driven by colored multiplication noise and colored addition noise, deduced the stationary state probabity density with outside noise relevant time τ accurately, and applied it to the symmetric potential well model. The result showed that internal and external noise have a strong coupling offect for the dynamic behavior of the system.
